ABSTRACT

Herein is disclosed a positional content platform and related systems and methods. According to some embodiments, the platform includes a mobile processing and communication device and a service layer executing on a server. The mobile processing and communication device communicates with the service layer. By virtue of the communication, a user of the mobile device is able to locate and view digital content that has been created and stored on the platform. The aforementioned content is associated with a geographic location, and, according to some embodiments, the content is represented in a user interface by an icon that is superimposed over a field of view representative of a geographic region.

RELATED APPLICATIONS

This application claims priority to U.S. Provisional Patent ApplicationNo. 61/470,961, “SYSTEM AND METHOD FOR LOCATIONAL MESSAGING,” filed onApr. 1, 2011, which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present document relates generally to a system and method fordelivery of digital content based upon the location of a particularrecipient, and more particularly to a system and method for delivering amessage to a mobile device, such as a cellular telephone, based upon thelocation of the mobile device.

BACKGROUND

Traditionally, the delivery of digital content (message forum postings,email, text messages, SMS, video files, graphics files, audio files,etc.) is organized around a universal resource locator (URL), telephonenumber or email address. In other words, when considering the questionof to where content is delivered, the answer is that content isdelivered to a particular URL (example: content is uploaded to aparticular image file server, such as the image file server atflickr.com, or to a particular video server, such as the one availableat youtube.com, or to a particular forum server, such as the oneavailable at 4chan.org), to a particular telephone number (example: atext message or SMS is delivered to a particular telephone number), orto a particular email address (content associated with emails aredelivered to a particular email address). One result of this presentstate of affairs is that content which is intended for receipt by acommunity is generally accessed by the community via a website. Thus,the community is nucleated about a website. Discussion pertaining to arestaurant, for example, is nucleated about a website such aschowhound.com, as opposed to being nucleated around the particularrestaurant that is the subject of the discussion. One disadvantage ofthis organization is that although a given individual may be a customerof the aforementioned restaurant, that individual will not encounter thecontent pertaining to the restaurant if he does not visit the particularwebsite that hosts the content.

There exists a need for a service that organizes the delivery ofelectronic content around physical location as at least one aspect ofits content delivery scheme.

SUMMARY

Against this backdrop, the present invention was developed. According toone embodiment, a computerized method for execution by a mobilecommunication and processing device includes displaying a user interfacethat presents a field of view representative of a region on earth. Themethod further includes sending a first service call to a service layer.The service call includes field of view data. In response to the firstservice call, attribute data descriptive of digital content that isassociated with a locale within said region is received. Additionally,an icon is positioned within said field of view of said user interfaceas a function of said locale.

According to another embodiment, a mobile communication and processingdevice includes a processor and a memory unit in communication with theprocessor. The memory unit stores a set of instructions that, whenexecuted by the processor cause the processor and memory unit tocooperate to display a user interface that presents a field of viewrepresentative of a region on earth. The processor also sends a firstservice call to a service layer, wherein said service call includesfield of view data. The processor also receives, in response to thefirst service call, attribute data descriptive of digital content thatis associated with a locale within the region. The processor alsopositions an icon within the field of view of the user interface as afunction of the locale.

According to another embodiment, a system includes a first mobilecommunication and processing device under operation by a first user.

DETAILED DESCRIPTION

FIG. 1 depicts one embodiment of a locational messaging system. As canbe seen from FIG. 1, the system 100 includes a plurality of mobilecommunication and processing devices 102 and 104. Although FIG. 1depicts a system including two mobile communication and processingdevices 102 and 104, the locational messaging system 100 may include anynumber of such devices 102 and 104, including very large numbers of suchdevices 102 and 104, such as millions of such devices 102 and 104, ormore. According to one embodiment, the mobile communication andprocessing devices 102 and 104 are embodied as smart phones, such as aniPhone® or a phone running the Android® operating system. According toanother embodiment, the mobile devices 102 and 104 are embodied aspersonal display assistant devices, tablet devices, mobile gamingdevices, or any other mobile device understood by those of skill in theart to provide a mobile execution environment with certain positionaldetection capabilities and communication capabilities, which arediscussed in greater detail herein.

According to one embodiment, each mobile device 102 and 104 maycommunicate with a positional content platform 106 via a communicationnetwork 108, such as the Internet. An application executing on themobile device 102 or 106 permits its user to generate digital contentand to associate that digital content with a location, so that thecontent can be encountered by another user of such a mobile device 102or 104. For example, a user of mobile device 102 creates a simple unitof digital content, a textual message, reading “I was here,” andassociates the message with a location. The user of mobile device 102may elect to associate the aforementioned message with his presentlocation L1. According to one embodiment, the mobile device 102 detectsits current location and associates the content generated by the userwith the current location. On the other hand, the user may elect toassociate his message with a location that is different from his currentlocation, such as at location L2. In either event, in the wake ofgenerating the content, the content and desired location for associationwith the content is communicated to the positional content platform 106.

Continuing with this example, the user of mobile device 104 uses themobile device 104 to discover and view the content. According to oneembodiment, the mobile device 104 presents a user interface having afield of view that corresponds with a region R1. According to oneembodiment, the mobile device 104 detects its current location, andbased upon its current location defines its field of view to begenerally centered about or to otherwise contain its location. As can beseen in FIG. 1, the mobile device 104 is located at location L3 andtherefore presents a field of view corresponding to region R1, whichencompasses location L3. An icon corresponding to the content associatedwith location L2 is presented within the field of view, at a locationwithin the field of view corresponding to location L2. Therefore, whenlocated at location L3, the user of the mobile device 104 observes, viathe field of view presented by the user interface, an icon alerting himto the presence of content associated with location L2. The user mayselect the icon, and view the message: “I was here.” According to someembodiments, the field of view may encompass an area that does notcontain the present location of the mobile device 104, and the field ofview may be selectable by the user of the mobile device 104.

According to some embodiments, the mobile device 104 sends a servicecall to the positional content platform 106 to obtain informationconcerning the location of content, so that icons may be properlypresented within the aforementioned field of view. According to someembodiments, the mobile device directs a service to the positionalcontent platform 106; the service call includes parameters defining theregion corresponding to the field of view. The positional contentplatform 106 responds by returning a data set that identifies each unitof content within the aforementioned region and the location associatedwith each such unit. This request and response transaction provides themobile device 104 with sufficient information to generate the field ofview and to place icons appropriately within the field of view, so thatthe location of the icons within the field of view correspond to thephysical location of the messages within the physical regioncorresponding to the field of view.

In response to having encountered and viewed the content associated withlocation L2, the user of mobile device 104 may generate a response, suchas, “So was I.” According to some embodiments, the response isassociated with the original message, so that the original message andcontent form a thread or discussion thread that is associated withlocation L2. The thread—also a form of content—is discoverable andviewable in the manner described above. Digital content to be associatedwith a location may take on any form, including, without limitation, theform of a textual message, a graphical image, such as a graphics filegenerated by the mobile device 104 via an integrated camera, a videofile, such as a video file generated by the mobile device 104 via anintegrated camera, such as an audio file generated by the mobile device104 via an integrated microphone, digital content for game, digitalcontent representing a discount or savings to be redeemed at a merchant,digital content representing a monetary value, a computer file, such asan executable program or data file, or any other form of digitalcontent.

According to some embodiments some content may be of more interest thanother content. For example, the user of mobile device 104 may have moreinterest in content generated by certain users, such those he knows,than by other users, such as those he does not know. The user may alsohave more interest in content that has been recently generated orchanged than he does in content that has been generated in the moredistant past. Similarly, the user may have more interest in content thathe has not viewed than in content he has already viewed. According tosome embodiments, to assist the user in discovering content suited tohis preferences, the mobile device permits the user to establish orselect filters that influence whether a given unit of content will berepresented as an icon within the field of view presented to the user.According to some embodiments, the mobile device directs a service callto the positional content platform 106; the service call includesparameters defining the region corresponding to the field of view, andfurther includes filter data (examples: date of creation of contentlater than a specified date, creator of content must be found within alist established by the user, content not previously viewed, etc.). Thepositional content platform 106 responds by returning a data set thatidentifies each unit of content that both satisfies the filterrequirements and is located within the aforementioned region. Thelocation associated with each such unit of content is also returned.This request and response transaction provides the mobile device 104with sufficient information to generate the field of view and to placeicons appropriately within the field of view, so that the icons actuallypresented in the field of view correspond to content satisfying thefilter requirements.

According to some embodiments, the system 100 includes a registrationprocess. The registration process requires a user to establish a username and a password, so that the user can later log into his account.The system also affords the user the opportunity to create anassociation between his own account and other users of the system 100.For example, the system 100 permits the user to assign a “friend” or“follower” or other relationship between his account and another user'saccount. According to some embodiments, these relationships may beimported from other platforms (example: “friends” may be imported fromFacebook®, and “followers” from Twitter®, etc.). According to someembodiments, these relationships may be used as filter criteria, so thatonly certain content ultimately ends up being represented as an icon ona user's field of view.

According to some embodiments, the system 100 presents an interface bywhich the user may define a region as a “place,” and may assign a nameto the place. For example, the mobile device 104 may present its userwith an interface allowing the user to define a place as the regiondetermined by the latitude and longitude of a given location L4, and aradius R1 extending from the location L4. According to some embodiments,the radius R1 may extend in two dimensions, while according to otherembodiments, the radius R1 may extend in three dimensions. According tosome embodiments, the mobile device 104 presents its user with aninterface by which its user may define a pair of latitudinal coordinatesLAT1 and LAT2 and a pair of longitudinal coordinates LONG1 and LONG2,thereby defining a place as the interior region defined by the pairs oflatitudinal coordinates LAT1 and LAT2 and longitudinal coordinates LONG1and LONG2. According to some embodiments, the mobile device 104 presentsits user with an interface by which its user may further specifyaltitude data, thereby defining a “place” as referring to a regiondefined as described above, at a particular altitude.

The system 100 allows a place or set of places to be associated with ause, so that the user can interact with a selected place in differentmanners. For example, one or more places can serve as filter criteria:represent as icons only those units of digital content associated withinthe region corresponding to a place prescribed by the user. Other usesof places, some of which are described herein, are also possible.

According to some embodiments, the system 100 provides notifications ofthe occurrence of certain events to the user. By way of example, andwithout limitation, a notification may take the form of a tone or audioindication from the mobile device 102 or 104, a vibration from themobile device 102 or 104, delivery of a notification to a “notificationcenter” of the mobile platform 102 or 104, presentation of a message onthe device's Lock Screen, presentation of a banner (optionally with amessage or number therein) superimposed over a button or icon, orpresentation of a badge superimposed upon a button or icon. According tosome embodiments, and by way of example, and without limitation, amobile device 102 or 104 may provide its user with a notification in theevent that: content was newly associated with a location in a defined“place”; that content was newly associated with a location within thefield of view of the user interface; that another user designated as a“friend” or “followed by” (or bearing some other relationship to theuser's account) has entered a location within a defined “place”; thatanother user designated as a “friend” or “followed by” (or bearing someother relationship to the user's account) has entered the field of viewof the user interface; that content has been created by another userdesignated as a “friend” or “followed by” (or bearing some otherrelationship to the user's account); that another user has responded toa unit of content that the user has created, such as by “replying” in athread. These notification are delivered asynchronously, being providedto the mobile device from the positional content platform 106 (in someinstances via an intermediary service offering “push” notificationservices), with the timing of the presentation of any particularnotification being a function of when the triggering event occurred, andwith the manner of presentation of the notification being a function ofthe configuration of the mobile device 102 or 104 and the state ofexecution of the application (example: the application is in theforeground, the application is in the background, the application isinactive, the device is asleep, etc.).

According to some embodiments, the system provides “newsfeeds” to theuser of the mobile device 102 or 104. In some embodiments, a newsfeed isa chronological queue of activity within the system 100 bearingcharacteristics that the action may be of interest to the user. The userinterface provides a screen that allows the user of the mobile device102 or 104 to view the newsfeed. According to some embodiments, eventsincluded in the newsfeed include those events that would trigger anotification. The occurrences of other events also are included in thenews feed, such as the number of responses in a thread surpassing athreshold, a “friend” registering as a user of the system 100, anotheruser followed by the user or who follows the user registering as a userof the system 100, etc.

According to some embodiments, the system 100 may access a publicapplication interface exposed by a social network or other externalplatform, in order to create a message (such as a “wall” posting, tweet,etc.) informing users of those platforms that a unit of content wasgenerated within the system 100. Optionally, the aforementioned messagemay include a hyperlink, permitting its viewer to select the link toview a webpage. The webpage referenced by the hyperlink may allow thevisitor to register for the service, or in the event that the visitor isalready registered, to log into his account, to view the content, or tointeract with the content (example: to respond to the content, as may bethe case in the context of a thread).

According to some embodiments, the platform 106 is programmed with a setof rules for conducting a game, the play of which is conducted at leastpartially through the encountering at a geographic location or region,viewing from or at a geographic location or region, placing at ageographic location or region or configuration of digital content to beplaced at a geographic location or region. The platform 106 furtherincludes rules and interfaces to permit encountering the game content,user reaction to such encounters, and manipulation of state variablesdefining a game's state in reaction to such encounters. The platform 106further includes rules and interfaces to permit viewing of the gamecontent, user reaction to such viewing, and manipulation of statevariables defining a game's state in reaction to such viewing. Theplatform 106 further includes rules and interfaces to permit placing thegame content in association with a geographic location, user reaction tosuch placements, and manipulation of state variables defining a game'sstate in reaction to such placements. The platform 106 further includesrules and interfaces to permit configuring the game content, userreaction to such configuration, and manipulation of state variablesdefining a game's state in reaction to such configuration.

FIG. 2 depicts a logical architecture of the positional content platform106, according to some embodiments. As can be seen from FIG. 2, thepositional content platform includes a service layer 200, a coredatabase application interface (API) 202, a logical data layer 204, aphysical data layer 206, and a web portal 208. Also depicted in FIG. 2is an application 210 executing on the mobile platform 102 and 104,which is referred to herein as the positional content application 210.

The positional content application 210 communicates with an API exposedvia the web services layer 200. The service layer 200 exposes API's tothe positional content application 210, permitting the positionalcontent application to cooperate with the positional content applicationto perform the operations and provide the features disclosed herein. Forexample, the web services layer may expose API's allowing creation ofcontent and association of the content with a location, allowingretrieval of content, allowing retrieval of attribute content within afield of view, allowing logging in or out of an account, etc.

Data constituting the positional digital content is stored in thephysical data layer 206, as is user account data and other data neededfor performance of the operations and features disclosed herein. Theservice layer 200 interacts with the data stored in the physical datalayer 206 through the core API's 202 exposed by the database server, andthrough stored procedures, schemas, and other tools pertaining to thelogical organization of the database 204.

According to some embodiments, the database 202, 204 and 206 is arelational database, while in other embodiments, it is embodied as anobject oriented database, or as a graph database. Optionally, thephysical storage layer 206 may be distributed, and may optionally bearranged so that data from users in a particular geographic region isdedicated to a particular storage array, or may be optionally arrangedso that content associated with a given geographic region is stored inone array, while content associated with another geographic region isstored in a different array.

By way of illustration, the positional content application 210 can makea service call to the service layer 200 to obtain information needed toposition icons representative of data within the field of viewprevailing in its user interface, as has been discussed with referenceto FIG. 1. The service call contains data from which the geographicalrange corresponding to the field of view can be determined, and mayoptionally contain filter data. The service layer 200 responds byinterpreting the service call, and breaking it into a series of core APIcalls to the core database API layer 202, causing the API layer 202 tointeract with the physical data storage layer to retrieve the requesteddata. The requested data is then passed to the service layer, whichpackages the data in a way appropriate for transport to and ingestion bythe positional content application 210. Finally, the positional contentapplication 210 responds by unpacking the returned data and positioningicons on the field of view, pursuant to the data returned by the servicelayer 200.

According to some embodiments, the service layer 200 also interacts withthird party platforms in order to perform the operations and provide thefeatures disclosed herein. For example, the service layer 200 optionallyinteracts with social platforms 212 to ingest user account data, such asfriend lists, follower lists, and to post messages on those platforms.Similarly, the positional content application also optionally interactswith third party platforms, for reasons ranging from obtaining map orsatellite imagery (discussed in more detail herein), for interactionwith an authorization engine, such as an o-auth engine, and for otherreasons required for the performance of operations and provision offeatures disclosed herein.

According to some embodiments, the service layer 200 interacts with anotification service 212. The notification service 212 is an externalplatform exposes an API that provides clients the ability toasynchronously communicate data messages to the mobile devices 202 and204. The notification service 212 interacts with the operating system onthe mobile device 202 and 204, in lieu of the service layer 200 directlyperforming such an interaction, in order to control the flow ofnotification calls directed to any given mobile device 202 or 204. Theservice layer 200 call the notification service 212 in order to providethe notification functionality discussed above and in greater detailbelow.

It will be understood by one skilled in the art that the executionenvironment for the positional content platform may be embodied as asingle platform. Optionally, each of the elements of the positionalcontent platform may be executed on separate servers, and any number ofthe elements may be executed on a single server or distributed acrossany number of servers. Optionally, the servers may operate as a clusterto permit greater availability and faster response times, as is wellunderstood in the art.

FIG. 3 depicts an exemplary embodiment of a mobile device 102 or 104,according to some embodiments. As can be seen from FIG. 3, the mobiledevice 102 include an applications processor 300 and a basebandprocessor 302.

FIG. 4 depicts a user interface 400 presented by the positional contentapplication 210, according to some embodiments. In the depiction of FIG.4, user interface 400 presents a screen that may be used for locatingcontent stored on the positional content platform 106. Given theparticular active screen in FIG. 4, the user interface 400 includes afield of view 402. The field of view 402 corresponds to a region ofgeography on earth. In the particular embodiment depicted in FIG. 4, amap is depicted within the field of view to help 402 the user determinethe particular region to which the field of view 402 corresponds,although this need not be the case.

As can be seen from FIG. 4, content icons 404 are superimposed over thefield of view 402. Each content icon 404 represents a unit of digitalcontent stored in the positional content platform 106. The position ofany given content icon 404 within the field of view 402 corresponds tothe geographic position associated with content represented by the icon.In other words, if a user of the positional content platform 106 electsto create content and associate it with the intersection of 50^(th)Street and France Avenue (or the longitude and latitude correspondingwith intersection of 50^(th) Street and France Avenue), then the contenticon 404 representing that content is positioned at the point within thefield of view corresponding to the intersection of 50^(th) Street andFrance Avenue. If a map is displayed in the background, the content icon404 appears at the intersection 50^(th) Street and France Avenue on themap.

Optionally, the color of a content icon 404 may be determined by certaincharacteristics of the content represented by the icon. For example, acontent icon 404 may appear in a first color, such as red, in the eventthat the content represented by the icon 404 makes reference to (or“tags”) the user account into which the positional content application210 is currently logged in. A content icon 404 may appear in a secondcolor, such as green, in the event that any unit of content representedby the icon 404 was created by a user account associated with thecurrently logged-in account (example: the underlying content containscontent created by a user account designated as a “friend,” “follower”or a user that the presently logged-in user account has designated to asa user account to “follow.”). A content icon 404 may appear in a thirdcolor, such as black, in the event that the content represented by theicon 404 has neither of the previously recited characteristics, and istherefore simply public content.

In the event that more than one unit of content is associated with thesame geographic position or very similar geographic positions, the fieldof view 402 could become cluttered with content icons 404 that interferewith one another. To prevent such cluttering, icons that would otherwiseinterfere with one another are represented by a single aggregator icon406. Several aggregator icons 406 are depicted in the field of view 402.Optionally, an aggregator icon 406 may bear a number on its face, withthe number representing the number of underlying units of content theaggregator icon 406 represents. According to some embodiments, the colorof an aggregator icon 406 may be determined by the characteristics ofthe various units of content is represents in a manner similar to thatdescribed with reference to a content icon 404. For example, anaggregator icon 406 may appear in a first color, such as red, in theevent that any of the units of content represented by the icon 406 makesreference to (or “tags”) the user account into which the positionalcontent application 210 is currently logged in. An aggregator icon 406may appear in a second color, such as green, in the event that any unitof content represented by the icon 406 was created by a user accountassociated with the currently logged-in account (example: any unit ofthe underlying content contains content created by a user accountdesignated as a “friend,” “follower” or a user that the presentlylogged-in user account has designated to as a user account to“follow.”). An aggregator icon 406 may appear in a third color, such asblack, in the event that the content represented by the icon 406 hasneither of the previously recited characteristics, and is thereforesimply public content.

FIG. 5 depicts a method for placing the content icon 404 and aggregatoricons 406 on the field of view 402. According to one embodiment, themethod of FIG. 5 is executed by the mobile device 102 or 104. Inoperation 500, a field of view 402 is displayed in the user interface400. As has previously been discussed, the field of view 402 correspondsto a geographic region of earth. In operation 502, a service call issent to the service layer 200. The service call may include field ofview data, so that the service layer 200 can determine the currentlyactive field of view in the user interface 400. In response to havingsent the service call, the positional content application 210 receives aresponse thereto. The aforementioned response includes data that isdescriptive of the individual units of content within the field of view402, including locational data for each such unit, and, optionally,other summary data for each such unit, including data required for icon404 and 406 color determination and information required for contentsummary display, as shown in FIG. 6.

Operations 508-518 can be performed as a single operation in the eventof a single unit of content being within the field of view 402, and inthe further event that the position and orientation of the mobile device102 or 104 is known, which may be the case, for example, if the positionand orientation was determined by user selection, as opposed tocorresponding to the actual physical location and orientation of thedevice 102 or 104, or, for example, if the position and orientation werepreviously determined. Given the aforementioned scenario, operation 506is performed by positioning an icon within the field of view 402 of theuser interface 400 as a function of the position associated with thecontent represented by the icon.

On the other hand, assuming that the conditions recited above are notsatisfied, operation 506 may be broken into operations 508-518. Inoperation 508, the position and orientation of the mobile device 102 or104 is determined, for example, through use of an on-board gyroscope andGPS unit integral with the mobile device 102 or 104. In operation 508,for example, through calls to location and rotation services in theunit's 102 or 104 operating system, information concerning the unit's102 or 104 latitude, longitude, altitude, longitudinal accuracy,latitudinal accuracy, vertical accuracy, and rotation around each of thex, y, and z axes may be determined.

In operation 510, the on-screen position of each icon is determined, asa function of the dimensions of field of view 402, the location of eachunderlying unit of content, and optionally the position and orientationof the mobile device 102 or 104 or chosen position for anchoring of thefield of view 402. In query operation 512, is determined whether any ofthe icons 402 or 404 would overlap one another. If not, operation 514 isperformed, and each icon 402 is superimposed on the field of view 402 inthe position determined in operation 510. On the other hand, if one ormore icons 404 or 406 would, in fact, overlap, then, in operation 516,the overlapping icons are “grouped” and represented as an aggregatoricon 406 until there exist no overlapping icons 404 or 406. Finally, inoperation 518, each icon 402 or 404 is superimposed on the field of view402 in the position determined in operation 516.

One of skill in the art will understand that the order of operationsshown herein need not be preserved, and that operations may be performedin different orders or concurrently.

For example, operation 500 and operations 502 may be performed in anyorder or at the same time. One of ordinary skill in the art willunderstand that other such operations may also be performed in sequencesother than those shown in FIG. 5 (or in any other Figure depicting amethod flow).

The user interface 400 also includes a series of selectable buttons408-416, the functions of each are the topic of further discussionherein, below.

The user interface 400 further includes a main menu button 418, theselection of which directs the user to a main menu allowing the user toperform various utilitarian operations not of interest in this document,but which will readily present themselves to the mind of one of ordinaryskill in the art (manage user account information, etc.).

The user interface also includes a selectable notification button 420,the function of which is the topic of further discussion herein, below.

The user interface 400 also includea a location button 422 the functionof which is the topic of further discussion herein, below.

The field of view 402 also a position indicator 424. The positionindicator 424 may be positioned as a function of GPS data, i.e.,positioned within the field of view 402 to correspond with the actualdetected location of the mobile device 102 or 104. As discussed below,certain features of the positional content platform associate content orotherwise function based on the position of the position indicator.According to some embodiments, the position indicator 424 always remainscentered in the field of view 402. The user may “swipe” his fingeracross the touch-screen of the mobile device 102 or 104 to scroll thefield of view 402 in the direction of his finger swipe. In that event,the position indicator 424 remains centered within the field of view402, so that the position indicator 402 effectively changes itsposition, thereby affecting certain functions and features of theplatform 106.

According to some embodiments, the content icons 404 are selectable.Upon selection of a content icon, a content summary 600 is displayed, asdepicted in FIG. 6. Typically, the unit of content will be a thread, inthat it will be constituted of a plurality of sub-units of content, eachof which is, in one form or another, a reply to the original sub-unit ofcontent. Together, each of the sub-units of content constitutes athread, or a single unit of content. The content summary 600 may includethe following data, each of which is optional: the user name of thecreator of the original sub-unit of content; the user name of thecreator of the most recently created sub-unit of content in the thread(or unit); an indication, in absolute or relative terms, of when theoriginal sub-unit of content was created; an indication, in absolute orrelative terms, of when the most recently created sub-unit was created;a picture or graphical image associated with the account of the creatorof the original sub-unit of content; a picture or graphical imageassociated with the account of the creator of the most recently createdsub-unit of content; an indication of the number of sub-units of contentin the thread; an indication of the number of creators of sub-unitswithin the thread that have been designated as being associated (as afriend/follower, etc.) with the user account currently logged in; anindication of the number of sub-units in the thread in which thelogged-in user account had been referenced (or “tagged”). The precedinglist is presented by way of example and not by way of limitation. Othertypes of summary data will readily present themselves to one of ordinaryskill in the art.

The content summary 600 includes a selectable close button 602, which,when selected, causes the content summary 600 to vanish from the userinterface 400. On the other hand, in response to selection of thecontent summary 600, the positional content application 210 causes theuser interface 400 to present a content detail 700, an embodiment ofwhich is depicted in FIG. 7.

As can be seen in FIG. 7, the content detail 700 presents a thread orunit of content, which is, in turn, constituted of sub-units 702, 704,706 and 708. Each sub-unit 702, 704, 706 and 708 has a creator that is auser registered on the positional content platform 106. Each sub-unit isintroduced into the thread depicted in FIG. 7 as either a response tothe original sub-unit of content 702, or as a response to anothersub-unit 704-708 in the thread. Optionally, the content detail 700 maypresent each sub-unit 702, 704, 706 and 708 in a sequential, indentedformat, with each sub-unit 702, 704, 706 and 708 being presentedbeneath, and indented to the right of, the particular sub-unit 702, 704,706 and 708 to which it is a response. Each sub-unit of content 702,704, 706 and 708 may include, by way of example only, and not by way oflimitation, textual information, graphical imagery, video imagery, audiocontent, and other forms of digital content, which will readily presentthemselves to the minds of those of ordinary skill in the art.

The content detail 700 also includes a selectable “back” button 710,when, when selected causes the positional content application 210 topresent the content summary 600, such as the one presented in FIG. 6.The content detail 700 also includes a selectable close button 712,which, when selected, causes the content detail 700 to vanish from theuser interface 400.

Each sub-unit of content 702, 704, 706 and 708 is presented with aselectable “reply” button 714 presented in a footer below the sub-unit702, 704, 706 and 708. Selection of the reply button 714 in the footerof a particular sub-unit 702, 704, 706 and 708 of content permits theuser to create a sub-unit of content for inclusion in the thread as aresponse to the particular sub-unit 702, 704, 706 and 708 of content. Toenable the user to create such response content, the positional contentapplication 210 presents a create comment screen 800 in the userinterface.

According to some embodiments, a content detail 700 or content summary600 or other unit of content associated with a location may be presentedto the user via the user interface, in response to the user entering aregion, without requiring the user to make any selection via the userinterface or otherwise perform any other action. For example, a messageor a coupon or other unit of content representing a discount or rebateto be redeemed or applied to a purchase may be associated with ageographic region. In the event that a user enters the region, thecontent is presented to the user. For example, a message instructing auser to travel to another particular region may be presented to the userin response to the user being detected within a region associated withthe message. After delivery of the message, if the user is detected inthe aforementioned other particular region, a unit of contentrepresenting a discount or coupon may be presented to the user via themobile device 102.

According to some embodiments, a unit of content may be completelyviewable by a particular user only if that user pays a fee, such as asubscription fee or a pay-per-view fee. For example, a particularcontent summary 600 may represent such a unit of content. In response toselection of the content summary 600, the user is presented with amessage explaining that the content, itself, or the content detail 700,is viewable or encounterable, only if the user first pays a pay-per-viewfee or subscription fee. Optionally, the message contains a link to aset of checkout pages that permit the user to tender payments. Inresponse to successful processing of the user's payment, the user mayselect the content summary, and encounter or view the underlying contentdetail 700 or content.

According to some embodiments, the positional content application 210determines its current location and orientation of the phone using theon-board GPS system and gyroscope, for example. For example, theapplication 210 determines that the mobile device 102 or 104 is locatedat the intersection of a particular latitude and particular longitude,and is oriented such that the rear surface of the phone is pointed 35°off of magnetic north. The application 210 then constructs a regionbased upon the detected position and orientation. The constructed regionserves as the field of view 402. For example, the application may createa region defined as the geographic space within a particular radius(example: 200 meters) of the current position of the device 102 or 104,and within a certain tolerance (for example, within ±15° of the detectedorientation). Carrying on the example, the constructed region is definedas: the set of geographic space within 200 meters of the currentlocation of the mobile device, and between 20° and 50° off of magneticnorth. The application sends a service call to the service layer 200 toquery the database 202 for content within the constructed field of view.In response to having sent the service call, the positional contentapplication 210 receives a response from the service layer 200. Theresponse includes data that is descriptive of the individual units ofcontent within the constructed field of view 402, including locationaldata for each such unit, and, optionally, other summary data for eachsuch unit, including data required for icon 404 and 406 colordetermination and information required for content summary 600 displayor aggregator summary 900 display. The application superimposes theicons 404 and 406 or summaries 600 and 900 on the display in a mannersimilar to that described with reference to FIG. 5. According to someembodiments, the vertical positioning of an icon 404 and 406 or summary600 and 900 is determined by the geographic distance between the currentlocation of the mobile device and location associated with the unit ofcontent reference by the icon 404 and 406 or summary 600 and 900. Forexample, icons 404 and 406 or summaries 600 and 900 referencingrelatively closer content may appear closer to the bottom edge of thescreen, while icons 404 and 406 or summaries 600 and 900 referencingrelatively further content may appear closer to the top edge of thescreen. According to some embodiments, the horizontal positioning of anicon 404 and 406 or summary 600 and 900 is determined by a polarexpression of the location associated with the content reference by aparticular icon 404 and 406 or summary 600 and 900. For example, aparticular unit of content may be positioned at a distance, d, from thecurrent position of the device 102 or 104, and at an angle, θ, from thedetected orientation. If the angle, θ, is close to zero, then the icon404 and 406 or summary 600 and 900 is presented close to the center ofthe screen. On the other hand, if the angle, θ, is close to theaforementioned negative or positive tolerance (carrying the previousexample forward: θ is close to ±15° from the detected orientation), theicon 404 and 406 or summary 600 and 900 is presented close to eitheredge of the screen.
